The shift in oxygen and air pressure at high elevations is one of the main causes.
Aircraft cabins are pressurised to the equivalent of 6,000–8,000 feet above sea level, which reduces oxygen levels, said Dr Hiran S. Reddy, consultant physician, diabetologist and critical care specialist, Gleneagles Hospital, Lakdi Ka Pul, Hyderabad. “This mild hypoxia can cause fatigue, headaches, and sluggishness, even on short-haul trips,” said Dr Reddy.
Furthermore, the cabin’s low humidity levels can lead to dehydration, dry skin, and general discomfort, all of which can exacerbate fatigue. “This affects energy levels and can cause dry skin, eyes, or throat. Sitting for prolonged periods with limited movement also reduces blood circulation, contributing to physical discomfort and fatigue,” said Dr Reddy.
Travel-related stress and discomfort also play a role. Dr Singla mentioned that cramped seating, long queues, and exposure to germs from fellow passengers can be physically and mentally draining. “For longer flights that cross multiple time zones, jet lag becomes a significant factor, as it disrupts the body’s internal clock and can cause fatigue, insomnia, and mood disturbances,” said Dr Singla.

To minimise flight-induced fatigue, it’s important to stay hydrated by drinking plenty of water before, during, and after the flight, while avoiding caffeine and alcohol, which can worsen dehydration.
“Moving around the cabin or doing simple stretches in the seat helps maintain blood circulation and reduces stiffness,” Dr Singla said.

Dr Singla advised that once you have arrived at your destination, ensure exposure to natural sunlight, which can help reset the circadian rhythm and ease jet lag. “One can also prepare in advance by gradually adjusting the sleep schedule to align with the destination’s time zone. Finally, practicing good hygiene, such as washing hands frequently and wearing a mask, can help protect against illness and maintain high energy levels,” said Dr Singla.
